atomic structure of feldspar

feldspar Properties, Uses, Types, Facts

Feldspar: Feldspar, any of a group of aluminosilicate minerals that contain calcium, sodium, or potassium. Feldspars make up more than half of Earths crust, and professional literature about them constitutes a large percentage of the literature of mineralogy.
